Trouble flared ahead of tonight’s Europa League game between Spurs and Lazio.

Italian newspaper La Repubblica reported scenes of “urban warfare” erupting in the early hours of this morning shortly after 1am in the Campo de Fiori with up to 100 “Ultras” - notorious troublemakers - attacking a band of Spurs fans.

Ten were left wounded with two stabbed, one of whom was believed to be critically ill. The violence is believed to have occurred at the Drunken Ship pub as fans of the London club were enjoying a drink.

Photographs show the pub wrecked.

The newspaper reported the Lazio fans were armed with knives, baseball bats, belts and knuckle dusters and they went on to “destroy” the venue.

One witness told the paper: “We feared the worst.”

It is believed police made some arrests at the scene.

A spokesman for the Foreign and Commonwealth Office confirmed they were investigating.
